FRANK X. MAIER AND PETER FRANTZ, OF STERLING, ILLINOIS, ASSIGNORS TO FRANTZ MANUFACTURING COMPANY, OF STERLING, ILLINOIS, A CORPORATION 0F ILLI- NOIS.

HASP-FASTENER.

To all whom t may concern Be it knownI that we, FRANK X. MAIER and PETER FRANTZ, citizens of the United States of America, and residents of Sterling, Vhiteside county, Illinois, have in vented a certain new and useful Improvement in Hasp-Fasteners, of which the following is a specification.

Our invention relates to hasp locks in general, but more particularly to those which are adapted to hang down when not in use, and which are provided with a pivoted latch for engaging the staple.

Generally stated, the object of our invention is to provide a novel and highly efficient hasp lock of this general character.

A special object is to provide a hasp lock that can be easily manipulated and operated by one hand, the pivoted latch thereof being readily controlled by the hand which holds the hasp, whereby the device can be locked and unlocked without using both hands.

Another object is to provide a hasp lock having a pivoted latch of such character that, inthe manufacture of these hasp locks, the pivotal end of one latch is blanked out between the locking arms of another latch, the opening between said arms and the said pivotal end portion having the same shape, whereby a saving in material is effected during the operation of blanking out these latches from sheet metal.

To these and other useful ends our invention consists in matters hereinafter set forth and claimed.

In the accompanying drawings: Figure 1 is a perspective of a hasp lock embodying the principles of our invention, shown in position between the fore finger and thumb of the head by which the device is both held and operated. Fig. 2 is a front elevation of the locking end portion of the said hasp lock. Fig. 3 is a diagram showing the manner in which the latches of the hasp Alook are blanked out from sheet metal.

As thus illustrated, our invention comprises a hasp A which consists of a straight strip of sheet metal with a staple slot a in'v the forward end thereof, and a hole a1 in its rear end, the said hole being utilized for fastening the hasp to the building. The latch B is pivoted to the hasp at b, between the slot a and the hole al, and is provided with a pair of arms 731 which are movable back and forth across the slot a, whereby the Specification of Letters Patent.

serial NQ. 738,522.

hasp lock is either a right or a left, only one of said arms being used if the lock is employed in a right hand manner, and the other arm being employed when the lock 1s used in a left hand way. Between said arms and the pivotal point of the said latch B, the latch is provided with upper and lower and outwardly projecting thumb and finger positions Z22, and between these thumb and finger positions, with a vertically disposed slot b3, which slot receives a stop or lug c2 formed on the outer surface of the hasp, the said stop serving to limit the up and down movement of the latch B about its pivotal point relative to the hasp. It will be seen that the distance between the outer surfaces of the portions b2 is the same, or substantially so, as the distance between the two parallel edges of the hasp A, whereby the grasping of the hasp lock, in the manner shown in Fig. 1, between the thumb and finger, at the point where the portions b2 project outwardly, serves automatically to center the latch relative to the hasp, causing the arms b1 to assume the position shown in the drawings. The latch B cannot move very far away from this position, simply far enough to disengage the arms from the staple, and consequently the portions b2 are always near enough to the upper and lower edges of the hasp to make it easy to grasp the two elements between the thumb and finger, causing them to be drawn into alinement in the manner shown and described. Thus, in locking and unlocking the hasp, only one hand is necessary, in the manner shown, which renders the operation of the device exceedingly convenient. It is a onehand hasp lock, practically speaking, and in addition is either a right or a left. As the portions b2 are not on the arms b1, it is not necessary for these portions Z22 to project beyond the upper and lower edges of the hasp, and consequently they can be near enough together to bring them into alinement with these edges when the latch is centered in the hasp, in the manner veirplained. Moreover, and as described, the latch is pivoted at a point between the staple slot and the attaching end of the hasp, rather than at the outer end of the latter, and in this way the latch is brought within the range of operation of the hand holding the hasp.

In addition, the opening between the arms o is of the same shape or outline as the portion 2f, which latter portion forms the means by which the latch is pivot-all)I nmunted. It thus becomes possible, in manufacturing these hasps, to blank the latches out from sheet metal in such manner that the portion b4 of one latch is made from the metal cut from between the arms of another latch, as shown in Fig. 3. In this way the metal cut from between the arms b1 is not wasted, but, to the contrary, goes to form the rear end or pivotal portion of another latch, and in this way a considerA able saving is effected, and less metal is rcquired for the manufacture of the device. This, of course, serves to reduce the cost of manufacture.

What we claim as our invention is:

l. A hasp lock comprising a hasp having a slot at the outer end thereof, a latch pivoted on said hasp, disposed between said slot and the other end of the hasp, provided with thumb and finger grasping means, said means being the saine in width as the adjacent portion of said hasp, to permit the hasp and latch to be brought into alinement between the thumb and finger, and means for limiting the motion of said latch relative to said hasp.

i2. A hasp loch comprising a hasp having a slot at the outer end thereof, a latch piv oted on said hasp, disposed between said slot and the other end of the hasp, provided with thumb and finger grasping means, said means being the same in width as the adjacent portion of said hasp, to permit the hasp and latch to be brought into alinement between the thumb and finger, and means for limiting the motion of said latch relative to said hasp, said latch having locking arms disposed at opposite sides of said slo-t.

A hasp lock comprising a hasp having a slot at the outer end thereof, a latch pivoted on said hasp, disposed between said slot and the other end of the hasp, provided with thumb and finger grasping means, said means being the same in width as the adjacent portion of said hasp, to permit the hasp and latch to be brought into alinement between the thumb and iinger, and means for limit-ing the motion of said latch relative to said hasp, said grasping means consisting of a pair of out-turned portions disposed even with the edges of said hasp, when the latch is in central position.

4f. A hasp lock comprising a hasp having a slot at the outer end thereof, a latch pivoted on said hasp, disposed between said slot'and the other end of the hasp, provided with thumb and finger grouping means, said means being the same in width as the adja cent portion of said hasp, to permit the hasp and latch to be brought into alinement between the thumb and finger, means for limiting the motion of said latch relative to said hasp, said last mentioned means consisting of a slot in the latch, and a lug on the hasp, extending into said slot.

5. A hasp lock comprising a hasp with a lug on the outer surface thereof, and a latch pivoted on said hasp, provided with a slot for said lug, the lug and slot permitting a limited movement of the latch, relative to said hasp, said latch having a pair of outturned portions, said lug and slot being disposed between said portions.

6. A hasp lool: latch provided with a bifurcated end forming a pair of locking arms, and having a rear or pivoted portion, the space between said arms having the same outline as said portion whereby the pivoted portion of one latch may be formed from the metal cut from between the locking arms of another latch, as and for the purpose set forth.

Signed by us at Sterling, Illinois, this 21 day of Dec., 1912.
